Does the surface make any difference in terms of condensation? I mean wavey walls vs flat walls? Mine have flat walls, so it will be a tight fit if you use something like rockwool. Spray foam is not available here, so I thought of using rockwool. Also, should I use some sort of vapor barrier, and then install rockwool on top of it?
How’s the toxicity/offgassing from closed cell spray foam?
